T 0 all cultomit may 05mm.- Be'it known that I, DARGY Columbus, in the county of'Bartholomew and State of Indiana have invented certainnew and useful Improvements in Oiling Devices; of which the following isa" specification.

This invention relates toimprovements in oiling devices; and of thatclass primarily used for oiling bearings, and is shown 111 the present instance as used in connection with the bearings of variable speed mechanisms, the prime feature of the invention'being-tlie provision 'o'f*m'eans for simultaneously lubricating a" combined radial and lateral thrust bearing. l A further featureof the inventionis in so constructing the lubricating means that it will automatically dispense thepoil onto the partsof the bearing in'uniform quantities; and further feature Of th'e inven-" tion is the provision of means for gathering the lubricant afterit has been dispensed onto the bearing partand'return the sameto the dispensing mechanismflhereby creating a constant circulation of the "lubricant through thc bearing and thelubricant dis- Other objectsandadvantages will be hereinafter more fully set forth and pointed out in the accompanying specification. In the accompanying"drawings I v a Figure 1 is a detailed; side elevation-of the bearing portion of a variable speed" transmission disk withparts showninsection. j I Figure 2' is asectional view seen onlineQ -QFigure 1. y a

Figure 3 is an enlarged detailedsectional view showing means forcreating aforce feed within the bearing.

Referring to thedrawlngs, 1 indicates a shaft upon which is mounted the usual, or any preferredvform of transmission disk 2, such as is used in connection with variable speed driving elements, the disk 2 having a hub 3 I integral therewith and extending late-rally therefrom and preferably splined to the shaft 1, so that the disk may have longitudinal movement with respect to said shaft but will be caused 'torotate therewith.

In the present form of device a housing 4 is entered over the hub 3, and at its inner end is provided with a circumferential cavity 5, in which is located a thrust bearing 6, the rollers 7 of said bearing having engage- Lnwnminmr a citizen 'of theUnited iStates,residing at thereof as v n i 3, one end of'thestrrp 1ft projecting'infthe ment with friction plates 8 and 9, bearing respectively against a shoulder 10 ontl e transmission disk 2 and the end wall of'the cavity 5, the housing '4; being so mounted upon the hub that it will move witlrthe hub although non-rotatable; consequently the hub has a radial hearing withinthe housing. a

Means may be provided {forintroducing i lubricant into the housing 4:, such as oil cups 11,-01', if preferred, but a'single oil Y p may be :used, which is preferably mounted upon that portion 'ofthe housing"- having the cavity-5' therein, so that th lubricant willenter'said cavity. To more evenly and uniformly distribute the lubricant over the radial bearing portion of the hub and housing, aswell asover the.

lateral thrust bearing parts; a reservoir 12 is formed lengthwise of thehousing a at a point below the shaft 1 and hub 3; said reservoir having direct communication with the periphery of the hub, so thatthe lubricant maycome'in direct Contact with the facc'of i the huh as the hub rotates." The reservoir other'absorbent substances that-may b'eused for absorbing and gradually feedingthe lubricant onto the face of the hub.

As the thrust bearing is so positioned that i the strip 13 cannot be eiitended into the path of the thrustbearing an additional strip of porous substance l l'is entered ins recess 15 in the eripheralface ofthe"hub path of the inner end portion of thestrip i 13, while the opposite 'endtliereof'extends across the path of the thrust bearing 6, the

strip l t-being preferably of lessporosity l than the strip 13, for better 'regulatingthe flow of the lubricant from thestrip 13 through the strip 14 onto the thrust bearing. By arranging lubricant feeding strips in this manner the lubricant will be gradually and uniformly fed onto the radial, as well In order to create a circulation of the lubricant and provide a substantially force pump action, a circumferential groove 16 is formed; in the peripheral face of the ill) shoulder 10, whichwill act to :collect and throw the lubricant onto the inner face wall of the cavity 5, from whence it will descend into the lowermost portion ofthe cavity,

in line with the reservoir :12, the centrifugal force created by the rotation of the disk causing the lubricant to flow towards and enter the porous strip 13, while a suction action on the strip 13 will be createdjby the revolution of the hub 3, thereby aiding in drawing the lubricant through, thev porous strip l3 and onto the bearingsurface- To more fully-guard against the ,lub ri-, cant escaping; from' the inner; end of the; housing, an inwardly extending lip,17 is formed at the outer end of the cavity 5, the

edgeof the lip terminating adjacentthe peripheral edge of the shoulder 10, andpar-.v tiallykoverhanging groove, 16. "The inner face of the lip 17 at its point'of union with thewall of the cavity 5, is preferably curved as shown at 18,' so that the lubricant will more readily flow away from the lip 17, and by extending the lip-inwardly a distance as shown the lubricant willinot escape between the-edge of th lip andthe shoulder adjacent which it terminates, said lip act-r ingIas a retaining wall for the lubricant.

aving'thus fully describedmy-said inventionfwhat I claim as new and'des'ire to secure by Letters: Patent, is:

1. 1The combination with the hub'of a variable speed transmission disk, of a thrust bearing housing surrounding said hub, an antifriction thrust bearing comprising a pair,;.of continuous washers ,ofrelatively hard material and antifrictionmembers be tween said washers, a lubricant reservoir in said housing, andmeans for distributing ,the'lubricant therefrom over faces.

- said bearing 2. The combination with a combined radial and thrust bearing, havinga reservoir therein, ofa fibrous material in said reservoir for dispensing the lubricant onto the bearin'g parts at a uniform flow, and means.

for collectingaand returning the lubricant to saidreservoir, and causing the same to circulate through the fibrousmateriah r 3., The combination with the hubofa variablespeed transmission dislnand a com bined radial and end thrust bearin mounted on said hub, said bearing having a lubricant reservoir therein, of a fibrous substance within said'reservoir adapted to distribute the lubricant over the face of the radial bearing surface.

4. The combination with, the hub, of a variable speed transmission disk, and a combined radial and end thrust bearing mounted on said hub,said bearing having a lubricant reservoirtherein, of a fibrous substance within said reservoir adapted to distribute the lubricant over the-face of the radial bearing surface, and means carried by said ,hubrfor'collecting' the-lubricant from the fibrous substance and distributingvthe same :over the end thrust bearing.

5. ,The combination with a variable speed transmission diskhaving an elongated hub projecting :from one. face thereof, of a, housing surrounding said Ihub, a thrust bearing encased within said housing, comprising a pairco'f 'continuousxwashers of relatively hard materiahwith antifriction members therebetween, a lubricant reservoir in said housing, and means for circulating the lubricant through the bearing and returning it to the reservoir.

6. Thercombination withthe hub of a variable speed transmission disk, ofa housing surrounding said hub, said housing having an enlargedend inwhich is formed a circumferential cavity and a lubricant reservoir communicating with the cavity, arrthrust bearing enclosedin said circumferential cavity, and a-n'inwardly' projecting flange for retaining the lubricant within thehousing and returning it to the reservoir.
